Vitopure  S3: soft water throughout your home

Viessmann S3 filters soften your domestic water by extracting minerals like calcium or magnesium to   prevent limescale and to increase the lifetime of your water-using appliance. At the same time, soft water is ideal for hair and skin care. S3 filters are high-capacity devices which are available at two or three cubic metre flow rate per hour.

Resin and salt for filtering and regeneration

Viessmann water softeners work through a process called ion exchange which eliminates minerals like calcium and magnesium from the water. Resin neutralizes the minerals. Given its smooth surface, it makes water purifiers run efficiently for a long time. Adding salt to the purifier enables the regeneration of resin - minerals are flushed away with waste water.
